Big week for Windows Phone as Mango rollout set to begin

The highly anticipated and well-reviewed “Mango” update to Microsoft’s Windows Phone operating system is expected to be available for some devices in the U.S. as early as this week — beginning a new bid by Microsoft to reverse its fortunes against the likes of Apple and Google in the mobile phone market.

Mango adds more than 500 new features, including upgraded Live Tiles on the home screen, better integration with third-party apps and new communications features. (See the Microsoft video below for an overview.)
